I am using Ubuntu 12.04 LTS. I have a LG CRT FLATRON E700SH model monitor, and whenever I log into Ubuntu I get a message saying:
OUT OF FREQUENCY HF:92.7kHz VF:58.0 Hz OPERATING FREQUENCY HF:30-70KHz VF:50-160 Hz
Please help me solve this problem if anyone knows it because I tried many of solutions. I have also tried switching to tty1 through Ctrl+Alt+F2 without success.
